The Basic Steps to Cast From Chrome
Casting from Google Chrome means sending video, audio, or your entire screen from your computer to a Chromecast device, smart TV, or compatible speaker. The process takes about 30 seconds once your devices are on the same Wi-Fi network. Open Chrome, click the three-dot menu in the top right, select "Cast", choose your device, and the content plays on your TV instead of your computer screen.
You do not need to install anything extra or sign into a special account. If you have Chrome and a Chromecast-compatible device already connected to your home Wi-Fi, you can cast right away. The only setup required is making sure both devices are powered on and joined to the same network.
Key Takeaways
- Click the three-dot menu in Chrome, select "Cast", then pick your device from the list that appears.
- You can cast a single tab, an entire window, or your whole screen — each option appears in the Cast menu.
- Both your computer and your Chromecast device must be on the same Wi-Fi network for casting to work.
- Once casting starts, you can close the Cast menu and keep using your computer; the content keeps playing on your TV.
- Casting uses your Wi-Fi connection, not a cable, so your computer does not have to be near the TV.
Finding the Cast Button in Chrome
The Cast button lives in the three-dot menu at the top right of your Chrome window. Click those three dots, and a dropdown menu appears. Look for the word "Cast" — it usually sits near the bottom of the menu, sometimes grouped with other sharing options. Click it, and a second menu pops up showing all the Chromecast devices on your network.
If you cast often, you can add the Cast button directly to your toolbar so you do not have to open the menu each time. In that same three-dot menu, find "More tools", then "Create shortcuts". You can pin the Cast button to your toolbar for one-click access.
Choosing What to Cast: Tab, Window, or Screen
When you open the Cast menu, you see three options at the top: "Cast tab", "Cast window", and "Cast entire screen". Each one sends different content to your TV. Cast tab sends only the active browser tab — useful for watching a video or presentation while keeping other work private on your computer. Cast window sends an entire Chrome window, so if you have multiple windows open, you choose which one appears on the TV. Cast entire screen sends everything on your monitor, including the desktop, other windows, and any notifications that pop up.
For most people, casting a tab is the safest choice because it keeps your desktop and other open windows off the TV. If you are presenting slides or showing a video, tab casting works well. If you need to show your whole desktop or switch between multiple windows during a presentation, choose "Cast entire screen" instead.
Making Sure Your Devices Can See Each Other
Casting only works when your computer and your Chromecast device are on the same Wi-Fi network. Check that both are connected to the same network name (SSID) — the network your phone or other devices use. If your computer is on a guest network and your Chromecast is on the main network, they cannot find each other.
If the Cast menu appears but your device does not show up in the list, try restarting your Chromecast by unplugging it for 10 seconds, then plugging it back in. Wait about 30 seconds for it to reconnect to Wi-Fi. If it still does not appear, restart your computer's Wi-Fi or forget and rejoin the network. Sometimes the devices need a moment to rediscover each other on the network.
Controlling Playback While Casting
Once casting starts, the content plays on your TV, but you control it from your computer. If you are casting a video, the play, pause, and volume controls on your computer keyboard work normally — pause on your computer pauses the video on your TV. You can also use the Cast menu to adjust volume or stop casting entirely by clicking "Stop casting".
While casting, you can minimize the Chrome window, open other tabs, or even close the Cast menu. The content keeps playing on your TV. If you need to switch what is being cast, open the Cast menu again and choose a different tab or window. The TV display updates to show the new content.
Stopping a Cast Session
To stop casting, open the Cast menu again and click the "Stop casting" button. The content disappears from your TV, and the Chromecast device returns to its home screen or idle state. You can also stop casting by unplugging the Chromecast or turning off the TV — the cast session ends automatically.
If you close Chrome entirely while casting, the cast session continues until you manually stop it or the device times out. This means you can close your browser and the video keeps playing on your TV, though you lose the ability to control it from your computer.
Troubleshooting When Cast Does Not Work
If the Cast button does not appear in your menu, make sure you are using an up-to-date version of Chrome. Open the three-dot menu, click "About Google Chrome", and let it update if needed. Older versions of Chrome sometimes lack the Cast feature or have bugs that prevent it from working.
If the Cast menu appears but your device is not listed, check that both devices are on the same Wi-Fi network and that your Chromecast is powered on. Look at your Chromecast device itself — if the light is off or blinking red, it may not be connected to power or Wi-Fi. Restart both devices and wait a full minute before trying again. If you still see no devices, restart your router by unplugging it for 30 seconds.
If casting starts but the video is choppy or keeps stopping, your Wi-Fi signal may be weak. Move your computer closer to the router or Chromecast device, or reduce the number of other devices using the network. Casting uses bandwidth, so a crowded network can cause playback problems.
Frequently Asked Questions
Can I cast from my phone or tablet to the same Chromecast?
Yes. Android phones and tablets can cast using the same Cast button in Chrome or other apps. iPhones and iPads can cast video from certain apps like YouTube and Netflix, though the process is slightly different. All devices must be on the same Wi-Fi network.
Do I need a Google account to cast?
No. Casting works without signing into any account. You only need Chrome, a Chromecast device, and a shared Wi-Fi network. If you want to use advanced features like remote casting from outside your home, a Google account helps, but basic casting does not require one.
Can I cast to a smart TV without a separate Chromecast device?
Many newer smart TVs have Chromecast built in. Look for "Cast-enabled" or "Chromecast built-in" in the TV's specifications. If your TV has it, the Cast menu in Chrome will show your TV as an option. Older TVs without built-in Chromecast need a separate Chromecast device plugged into an HDMI port.
What happens if I move my computer far from the TV while casting?
Casting uses Wi-Fi, not a direct connection, so distance does not matter as long as both devices stay on the same network. You can take your computer to another room and the video keeps playing on the TV. If you move far enough that your computer loses Wi-Fi signal, the cast session stops.
Can I cast audio to a Chromecast speaker?
Yes. If you have a Chromecast Audio device or a smart speaker with Chromecast built in, the Cast menu shows it as an option. You can cast music, podcasts, or any audio from Chrome tabs to the speaker the same way you cast video to a TV.
